git remote add upstream git-repository-url

Adds remote git repository represented by git-repository-url as new remote named upstream to the git repository

Assuming you set the upstream (as in the "setting an upstream repository")

git fetch remote-name
git merge remote-name/branch-name

The pull command combines a fetch and a merge.

git pull

The pull with --rebase flag command combines a fetch and a rebase instead of merge.

git pull --rebase remote-name branch-name

git ls-remote is one unique command allowing you to query a remote repo without having to clone/fetch it first.

It will list refs/heads and refs/tags of said remote repo.

You will see sometimes refs/tags/v0.1.6 and refs/tags/v0.1.6^{}: the ^{} to list the dereferenced annotated tag (ie the commit that tag is pointing to)

Since git 2.8 (March 2016), you can avoid that double entry for a tag, and list directly those dereferenced tags with:

git ls-remote --ref

---

It can also help resolve the actual url used by a remote repo when you have "url.<base>.insteadOf" config setting.
If git remote --get-url <aremotename> returns https://server.com/user/repo, and you have set git config url.ssh://[email protected]:.insteadOf https://server.com/:

git ls-remote --get-url <aremotename>
ssh://[email protected]:user/repo

To delete a remote branch in Git:

git push [remote-name] --delete [branch-name]

or

git push [remote-name] :[branch-name]

If a remote branch has been deleted, your local repository has to be told to prune the reference to it.

To prune deleted branches from a specific remote:

git fetch [remote-name] --prune

To prune deleted branches from all remotes:

git fetch --all --prune

Output some information about a known remote: origin

git remote show origin

Print just the remote's URL:

git config --get remote.origin.url

With 2.7+, it is also possible to do, which is arguably better than the above one that uses the config command.

git remote get-url origin

List all the existing remotes associated with this repository:

git remote

List all the existing remotes associated with this repository in detail including the fetch and push URLs:

git remote --verbose

or simply

git remote -v

Syntax for pushing to a remote branch

git push <remote_name> <branch_name>

Example

git push origin master

You can create a new branch and switch to it using

git checkout -b AP-57

After you use git checkout to create a new branch, you will need to set that upstream origin to push to using

git push --set-upstream origin AP-57

After that, you can use git push while you are on that branch.

To change the URL of the repository you want your remote to point to, you can use the set-url option, like so:

git remote set-url <remote_name> <remote_repository_url>

Example:

git remote set-url heroku https://git.heroku.com/fictional-remote-repository.git

Check existing remote

git remote -v 
# origin https://github.com/username/repo.git (fetch)
# origin https://github.com/usernam/repo.git (push)

Changing repository URL

git remote set-url origin https://github.com/username/repo2.git
# Change the 'origin' remote's URL

Verify new remote URL

git remote -v
# origin  https://github.com/username/repo2.git (fetch)
# origin  https://github.com/username/repo2.git (push)

To rename remote, use command git remote rename

The git remote rename command takes two arguments:

• An existing remote name, for example : origin
• A new name for the remote, for example : destination

Get existing remote name

git remote
# origin

Check existing remote with URL

git remote -v 
# origin https://github.com/username/repo.git (fetch)
# origin https://github.com/usernam/repo.git (push)

Rename remote

 git remote rename origin destination
 # Change remote name from 'origin' to 'destination'

Verify new name

git remote -v 
# destination https://github.com/username/repo.git (fetch)
# destination https://github.com/usernam/repo.git (push)

=== Posible Errors ===

1. Could not rename config section 'remote.[old name]' to 'remote.[new name]'

   This error means that the remote you tried the old remote name (origin) doesn't exist.

2. Remote [new name] already exists.

   Error message is self explanatory.

You can change the url of an existing remote by the command

git remote set-url remote-name url 

You can obtain the url for an existing remote by using the command

git remote get-url <name>

By default, this will be

git remote get-url origin
